Information about Västerås
Västerås is Sweden’s 6th largest city and in the municipality (the city and the surrounding areas) there are about 150.000 inhabitants. It is also one of the oldest towns in the country and was an important town in Medieval Sweden. When the steel industry developed in Sweden, in the 13th century, Västerås became an important port town, situated on Lake Mälaren which is connected to the Baltic Sea.
During the industrialisation era in the 19th and 20th centuries, Västerås again developed a lot and several companies were started here: ABB (originallly called as ASEA) and H&M probably being the most internationally well-known ones. Today, Västerås is a nice place to visit.
